Far Out: German Study Finds Pulsing Wind Farm Infrasound 20 Kilometres From Turbines

Overrun by 30,000 or so giant industrial wind turbines, it’s no surprises that Germans know all about the misery of wind turbine noise.

A component of the cacophony of low-frequency, amplitude modulated noise generated by these things occurs in frequencies meant to be below what humans can ordinarily hear. But that does not mean that they can’t sense what’s referred to as ‘infrasound’.

The evidence proving the unnecessary damage done to wind farm neighbours by the noise generated by giant industrial wind turbines is mounting by the day: Germany’s Max Planck Institute has identified sub-audible infrasound as the cause of stress, sleep disruption and more (see our post here); and a Swedish group have shown that it’s the pulsing nature of low-frequency wind turbine noise  (‘amplitude modulation’) that is responsible for sleep problems in those forced to live with it (see our post here).

The Finns have found that that the safe setback distance is more like 15,000m, than the 1,000m or so that risible planning rules permit (see our post here).

Following the Finns, a team of German researchers have taken to the field to not only document the unrelenting (and wholly unnecessary) suffering of wind farm neighbours across Germany, but to gather a detailed dataset of precisely what it is that their fellow countrymen are being exposed to. And at distances of over 20km!

Wind turbine infrasound as a weapon
Chautauqua Updates
18 January 2019

Industrial wind turbine infrasound is not the best weapon, but it is a weapon. This German video documents the harmful effects of the infrasound produced by industrial-sized wind turbines.

The dangers of infrasound have been known since the 1980s when the U.S. military heavily invested in infrasound (below 20 Hz) as a weapon. It looked like it had great promise, according to Col. John B. Alexander who was involved in weaponizing it.

The military gave up on infrasound as its effects on people were too random: some potential targets were seriously debilitated; others not so much. This video presents various studies by acoustical engineers and other scientists showing infrasound’s affect on the ear, the heart, the brain and other organs.



Narrator: Infrasound occurs where large masses are in motion. This happens in nature with avalanches and earthquakes, for instance. But infrasound also arises through technology and industry. It’s caused by large machines and blasting. Even wind turbines generate infrasound whenever their blades rotate. In a densely populated country like Germany, where wind farms border on residential areas, many people are robbed of their sleep.

Insa Bock: It’s worse when I lie in bed at night. After five or 10 minutes, I feel kind of dizzy. My heart starts to race and I get this massive ringing in my ears. To some extent, I also feel claustrophobic and stressed.

Narrator: Insa Bock and Hermann Oldewurtel live in East Frisia near the town of Esens. Located scarcely 700 metres from their home, is a wind farm with a few dozen wind turbines. Since they function even at low wind speeds, the wind park is in operation virtually 24-7.

Hermann Oldewurtel: If you sleep here for four or five days, you feel like you’ve been out drinking for a whole week. It’s that bad. You get those total mental blank outs. It’s even happened to me on the phone. I couldn’t believe it, but if I’m out and about, or if I go away for a few days, I’m as right as rain again.

Narrator: At first, it wasn’t certain what was causing the health issues. Wind farms have existed here for more than 20 years, so they didn’t seem to be the problem.

Narrator: It took a while for us to realise that our health problems were being caused by wind power. Even we didn’t believe it at first. We’d always had a small wind farm on our doorstep, with 52 units.

Insa Bock: We found them annoying. Sometimes, they were so loud, that we could hear them very clearly. But it’s not as if the noise made us feel ill.

Narrator: Similar to other people living next to wind farms, problems were the result of re-powering. That’s when small wind turbines are replaced with bigger, more efficient models. It’s a development welcomed by the German Environment Agency, as part of energy transition. Officials here are not overly concerned at the infrasound from wind farms. They refer to tests carried out in the state of Baden-Wurttemberg.

Thomas Myck: These tests show that when a wind farm is situated around 700 metres from a residential area, the infrasound from it, is drowned out by background noise. In other words, a perfectly normal noise level arises, from which it is no longer possible to filter out the specific features of infrasound.

Narrator: This is what the situation looks like in chart form. From a distance of 700 metres, the infrasound from wind farms, shown here in red, can no longer be distinguished from the infrasound of the background noise, shown in green. The red graph has no peaks, no upward deflections. Infrasound is also measured in Bavaria, however in order to identify possible explosions from nuclear weapons. Here, the Federal Institute for Geosciences and Natural Resources, the BGR, operates a measuring station, the I26DE, on behalf of the German government.

Narrator: The I26DE is part of an international monitoring network designed to ensure that the terms of the comprehensive nuclear test ban treaty are observed. The BGR achieves this with ultra sensitive measuring systems. Looking more like shower heads than high tech equipment, the inlets for the infrasound are located close to the ground, where the rushing of the wind is least noticeable. Wind noise would affect the readings. The heart of the system is located a few metres underground. Garden hoses conduct the infrasound signals from the various inlets to a microbaromter. It measures minute pressure differences, the infrasound.

Lars Ceranna: The measuring systems we have, can determine the difference in air pressure between the upper and lower surfaces of a sheet of paper, even down to one 40th of its thickness. That’s how accurate our measuring systems are.

Narrator: Extremely precise and thus also sensitive to infrasound signals generated by technical sources.

Narrator: The lake Mohne hydroelectric power station is located nearby. When a lot of water is released, that’s also a factor. Wind farms are another source we know about.

Narrator: So the infrasound from wind farms could affect the measurements taken by the I26DE Station. Because of this, back in 2004, the BGR examined the infrasound emissions from a single wind turbine. The scientists were mainly interested in assessing how far from the wind turbine, it would still be possible to register infrasound emissions. Their measurements were analysed at the BGR’s National Data Centre. Lars Ceranna comments on the frequency spectrum.

Lars Ceranna: At low frequencies, our infrasound sensors picked up very clear signals from the wind turbine. Every time the blade passes the tower, large air volumes are compressed and sheared. This signal produces an infrasound signature which we refer to as blade pass harmonics.

Narrator: The blade pass harmonics of the wind turbine are individual frequencies. They emerge from the background noise, with a distinctly higher acoustic pressure level. In other words, with more energy. Las Ceranna explains.

Lars Ceranna: If we follow the blue line with the mouse, that is the background noise. The distinctive elements of it here, represent the contribution from the wind energy plant. The blade passing harmonics, when the blade passes the tower, and generates an infrasound signal

Narrator: The wind turbine studied in 2004 was very small, barely 0.2 megawatts. For bigger wind farms, the scientists made a model calculation.

Lars Ceranna: It takes us to a dimension, where we can say that a five megawatt wind turbine, would possibly generate a detectable infrasound signal, even from a distance of 20 kilometres.

Narrator: 20 kilometres. But didn’t they claim that the German Environment Agency, that the infrasound emissions from wind energy plants, are already lost in the background noise, from a distance of 700 metres? So how can this huge difference be explained?

Lars Ceranna: It’s customary in acoustics to focus on bands. In other words, on groups of frequencies and not on the individual frequencies.

Narrator: Just how this affects the data, can be explained with different curves. The blue line represents the unembellished data, and shows clear peaks.

Lars Ceranna: If I focused on bands, I’d have a red curve here, with the peaks quite clearly evened out.

Narrator: Thus a graph flattened to such a degree, provided the German Environment Agency with the argument that infrasound from wind farms, is swallowed up by the background noise. Back to East Frisia. The house where Insa Bock and Hermann Oldewurtel live, is both their home and their workplace. So selling it, is out of the question. After initially promising to carry out measurements, the authorities responsible then declined.

Hermann Oldewurtel: We were informed that it would not be possible to carry out the tests at the time, because the wind direction and wind strength were not right.

Narrator: Left in the lurch by the authorities, the couple commissioned the measurements themselves. They were carried out by expert Sven Johannsen. Amongst other things, he used a vibration sensor, because wind power plants also generate structure-borne sound. In other words, vibrations. Johannsen compared the structure-borne sound pattern of the wind farm with that of the house.

Sven Johannsen: It’s like comparing fingerprints. You can prove which source something was triggered off by. In this case, we suspected the wind turbine.

Narrator: Microphones measure the interior and outside areas. A microbarometer records minute air pressure fluctuations. All the appliances are synchronised to register infrasound and structure-borne sound simultaneously.

Sven Johannsen: When powerful vibrations occur, as a rule, even minimal acoustic pressure in the air-borne noise range is sufficient to cause discomfort. If there were no vibrations, the acoustic pressure could be a bit higher before it’d have this effect. So here, we have interaction between structure-borne sound and normal air-borne noise. That’s why it’s important to look at both at the same time.

Narrator: Vibrations, then, increase sensitivity to infrasound, an additional burden for residents.

Insa Bock: When I was lying in bed, I actually noticed the vibrations on the mattress. I had this strange feeling that something was wrong. Then in the half-light, I clearly saw the mattress move several centimetres.

Insa Bock: When the buzzing starts, it’s like you are in a beehive. You just need to put your hand on the wall of the house, and feel the vibrations.

Insa Bock: When it’s really windy, the dog also feels the vibrations. It becomes restless, then it’s favourite sleeping spot is in the wardrobe. Even if the door is closed, the dog will open it and climb in. That way, I think, it is no longer lying directly on the vibrations.

Narrator: Sven Johannsen also experienced the occurrence of vibrations.

Sven Johannsen: The measurements showed a clear load in the form of powerful vibrations. We even noticed this ourselves when we were standing next to the house. To a certain extent, our technical measuring equipment also detected these vibrations inside the house.

Narrator: Along with the vibrations, Johannsen also registered a distinct infrasound load.

Sven Johannsen: Extremely high infrasound levels were also detectable inside the house. To some extent, the acoustic pressure levels were even higher than in the outdoor area.

Narrator: A survey by the authorities would have produced a different result, because it would have been performed according to DIN 45680 (German Standard). So the infrasound range would have been largely ignored, and individual frequencies combined, thus smoothing off any peaks. The basic problem with this DIN, is it’s simple assumption that anything below 20 hertz, is imperceptible to the human ear. But there are justified doubts as to whether this is true.

Narrator: Professor Alec Salt works at the Washington School of Medicine, in St Louis, in the United States. He is an internationally recognised expert on the physiology of the inner ear, and for some time now, on the fact that the ear reacts to infrasound. It’s an observation Salt and his team made more by chance in carrying out research into a disease of the inner ear. The doctors used infrasound to test how the diseased ear reacts to external stimuli.

Alec Salt: We discovered that if you went down to very, very low frequencies, your results got better. So instead of having a sound you can hear like 30, 40 hertz, we went down and down and down. And we discovered even 5 hertz was getting lovely results.

Narrator: The researchers wanted to get to the bottom of this surprising discovery. Why did the ear react to the signal even though it was inaudible? The answer lies in the complex anatomy of our ear, which amongst other things, is equipped with two different types of sensory ear cells.

Alec Salt: When a human is exposed to infrasound, that sound is going to go into their ear. It’s going to stimulate their outer ear cells. It’s not going to stimulate their inner ear cells, which are the ones they’re hearing through. So they’re not… They don’t hear the sound at all, but there’s still electrical responses in the ear, to the sound. And that is still stimulating another pathway.

Narrator: Based on his own observations and on an intensive study of specialised literature, Salt’s findings are regarded by colleagues as undisputed, but that is not the case outside the world of science.

Alec Salt: Lawyers who have gone beyond the advisors to the wind turbine people, are extremely against this paper. They have given us a hard time for many years. I mean, we get trashed in law suits of how this is not possible and all this sort of thing. But somehow the sciences disagree with this. I think if you want to biassed, it’s all to do with bias and money, I’m afraid.

Narrator: For Professor Salt, the scientific questions concerning infrasound and human perception, have by no means, been fully answered. That’s why considers it important for more research to be carried out in this field. And that is precisely what is happening at Medical Centre Hamburg-Eppendorf. Does infrasound affect the sleep and the mental capacity of human beings? An experiment, it is hoped, will provide answers. Clinical psychologist, Dr Leonie Ascone is installing loudspeakers in the rooms where test persons will be sleeping.

Narrator: The volunteers in the infrasound test group will be exposed to low frequency sound for four weeks. The exposure will take place at night, with 90 decibels of relatively high intensity. Before and after each test phase, the volunteers will be subjected to complex examinations, like a hearing test and their action times recorded.

Narrator: The aim is to show what effect four weeks of exposure to infrasound has on the test persons.

Narrator: This study is the continuation of an earlier experiments. Scientists, Professor Simone Kühn and her colleagues had exposed test persons to brief infrasound signals below the auditory threshold. In other words, sound they couldn’t hear. The researchers then took a look at what happened in the brain.

Simone Kühn: What was interesting to note was that conditions with infrasound exposure, close to the auditory threshold are somehow special. Intense activity took place in the anterior cingulum, a region of the brain which deals primarily with conflict situations, and also in the right amygdala, the region which is linked to stress management.

Narrator: So of all things, infrasound activates regions of the brain which normally manage stress. But it’s not quite clear why.

Simone Kühn: We’ve also speculated that if you consciously hear something and realise there is something, you might block it out and say, “I’m going to ignore that.” But with things that are semi-perceptible, you don’t have the ability to say, “I’m going to ignore it.” That’s our theory.

Narrator: So what we consciously hear can be assessed and if necessary, ignored. But things that are only perceived subliminally, in other words, subconsciously, generate stress and perhaps even fear. Someone who knows all about this, is John B Alexander, a former US Army Colonel. He fought in Vietnam, became a member of the US Special Forces, and later, he headed a department which focused on the development of unorthodox weapons.

Narrator: After the 1980’s at the latest, they included infrasound.

John B. Alexander: The first question was, are the effects that we’re reading about real? And what you found is, yes. There were some people who were physiologically affected. They were nauseous. They would get dizzy. There were some who had psychological issues, fear factors, inability to think, kinds of things.

Narrator: Effects that the US Military thought that could be used well against an enemy. Prototype infrasound weapons of monstrous dimensions were then developed, along with infrasound test chambers for animal experiments using rhesus monkeys. Other powers also expected great things from infrasound as a weapon.

John B. Alexander: Remember, when we started, we’re talking 1980’s, we’re talking the bad old days. So we’re talking the Soviet Union still exists. Getting data out of Soviet resources was extremely difficult. But there were reports, like controlled defensive behaviour the DIA had, that suggested that they were looking in that area. My experience with the Chinese had been the same. They looked across a wide, wide range of technologies.

Narrator: In the mid 2000’s, at the latest, the idea of putting infrasound to military use, was abandoned. The problem was the technology and the fact that infrasound does not affect everyone in the same way. For military commanders, that is unacceptable.

John B. Alexander: We found that some people are affected dramatically. Some people are affected a little bit, and others not at all. From a weapons perspective, I shoot a bullet, I know what it’s going to do to your body. As a commander, if you’re going to have a weapon, you want something that when I pull the trigger, I know exactly what the effects are going to be, or can have a pretty close approximation.

Narrator: The military has lost interest in infrasound, but medicine hasn’t. Inaudible sound is attracting more and more research. Professor Christian-Freidrich Vahl is Director of Cardiac, Thoracic and Vascular Surgery at Mainz University Medical Centre. Over the last two years, he and his team have devoted their research to the subject of infrasound. The focus is on the acute effects. The researchers are studying human heart muscle fibres. For this experiment, two fibres from the same patient are isolated. Only a few millimetres in size, the specimens are still alive.

Narrator: They are secured into identical pieces of equipment. One will serve as a control, the other will be exposed to infrasound in the form of a 16 hertz frequency for one hour. The aim is to measure how the strength of the heart muscle fibre changes under the influence of infrasound. This is already the third series of tests, carried out by the work group. Two earlier series have already been concluded.

Christian-Friedrich Vahl: We can definitely say that under these acute conditions, infrasound really does have a distinct effect on heart muscle tissue. Both series of tests have revealed a clear reduction in heart muscle strength.

Narrator: Here in the laboratory too, the low frequency sound cannot be heard, at least not consciously. It becomes visible when Dr Ryan Shabban holds a sheet of paper in front of the loudspeaker. It is not yet clear just how infrasound manages to reduce the strength of the heart muscle, but one theory has already been put forward.

Christian-Friedrich Vahl: Think of a rowing boat with rowers in it. They are the cross-bridges of the muscle. If this rowing boat is now exposed to an infrasound signal and suddenly starts to shake, if it were an eight maybe, four of the crew would continue rowing. But the four others would get out of step, and in a jiffy, the boat would lose speed.

Narrator: What causes the rowing boat, or to be more accurate, the heart muscle, to get out of step, is the energy of the infrasound.

Christian-Friedrich Vahl: Whether we hear it or not, every form of energy has physical effects, and infrasound is particularly dangerous, because we don’t hear it.

Narrator: It is the duty of the federal government to protect its citizens from harmful environmental influences. The Federal Emissions Control Act stipulates how this has to happen, and to what extent. First and foremost, the Act refers to significant influences.

Thomas Myck: The Act does not claim to cover every type of negative influence. So there can most certainly be cases where for instance, someone feels affected by a source of noise in a way or to a degree, that the Act does not cover. When a law is made, the legislature always leaves a small area which the law does not cover. And this is something citizens simply have to accept.

Narrator: Simply to accept, is no option for Insa Bock and Hermann Oldewurtel. They feel left in the lurch by politicians, betrayed, in fact.

Insa Bock: They show absolutely no consideration for nearby residents. They just make sure that wind park operators are fine, that their wind farms are approved, and they can build them and make profit, with taxpayers money, of course. Because we also contribute to all this subsidised electricity.

Narrator: The two seek respite on a camping site far enough away from their house and the wind farm. This is where they spend their evenings, but especially the nights, in order to get some sleep.

Christian-Friedrich Vahl: When I reflect on everything we have read so far, I believe that if we are not careful, we could turn into a land of insomnia, full of tired citizens who are exposed to signals they cannot hear, thus cannot protect themselves against.

Narrator: Insomnia, heart problems, perception disorders, dizziness. These are just a few of the disease symptoms that can be caused by infrasound. Doctors believe that between 10 and 30% of people react to it. And that means, several million in Germany alone. Nevertheless, the mass experiment with wind power continues unabated.

    I have been keeping an eye out for this program online for a while now.

    The YouTube channel SPARK have published the program Windfarm Wars. It is compelling viewing and highly recommended. I hope that it is available to view in most countries.

      It would appear that outside forces are already trying to take down Windfarm Wars! If you want to see it, you may have to hurry. In the third episode, which has been removed, RES were eventually given permission to build the wind farm.

      But there was a sting in the tail.

      They would have to monitor AMPLITUDE MODULATION!

      As is stated in the program, Amplitude Modulation or AM is effectively death for onshore wind farms.

  5. Jackie Rovensky says:

    The work to uncover the dangers of this industry began with the efforts of a very few, who did not wither under the denigration of self interested academics and other professionals. They stood tall doing what they could to help those suffering who found it hard to find people who would believe them.
    Slowly at first the work was tough and time consuming but they did not give in. Eventually things began to change as more people spoke out about their illness while living near these Monsters and these things were getting bigger and stronger as NO Government had the guts to stop the industry from taking control of our regulatory systems and our lands.
    But the work continued and more researchers became willing to undertake research into the cause of the suffering, they looked for what could cause it and where they found something they looked further to see why that caused such pain. The world of the Industrial Wind turbine and its industry and followers began to crumble at the edges.
    As time has gone on that crumbling is becoming wholesale avalanches of distrust and uncertainty.
    There is no Nocebo or even ‘factoid’ in what is going on as research is increasingly showing these ‘fabled’ utterances are nothing more than attempts to stop the decay and to destroy the reputations of those working to find the cause of the reported pain and/or to support those suffering.
    They failed in their attempts and those they attacked are still there working together as more people come forward reporting their years of anguish, pain and suffered with no cause being found, and in some cases people being told they are ill just because they don’t like the look of the turbines or are not receiving any financial gain from them.
    As this industry has been shown to have known of the dangers it posses years ago and tried to hide their knowledge they are becoming increasingly seen as and industry without ethical standards.
    This so called Green industry is rancid and it’s dying and moving toward an increasingly speedy death.
    It’s time for our Governments to take back control and issue stringent Regulations that ensure the safety of their citizens, and to stop this industry from committing wholesale destruction of peoples lives FOR NOTHING MORE THAN TO FILL THEIR POCKETS WITH MONEY.
    To those who began the push against the industry, those who exposed the lies, those who are and have been undertaking Research for so long now WE THANK YOU for your persistence. To those who will join the push to regain the rights of every citizen to live and work in peace and good health where they wish to WE THANK YOU.
    To those who have suffered for so long WE WISH YOU A FUTURE FREE OF PAIN SOMEWHERE SAFE FROM HARM.
    Everyone should remember there is no machinery that cannot cause harm, none is completely safe, that is why Standards and Regulations are meant to be independently created and updated as soon as necessary with independent inspectors and experts who can recognise when a machine is failing in its Safety requirements.
    A machine can be as dangerous to human health as poisoning or chemical spill.
    Finally Governments should consider removing subsidies and not provide more to this industry – could it be concluded that the unwillingness to admit it had knowledge of the danger of adverse health effects on people for many years is valid reason to bring about cessation of such subsidies.
    And should the UN be sanctioned for demanding a reduction in emissions from energy production and other things without first ensuring such a move would not cause harm, financial or medical?

    • Sommer says:

      Forcing people to leave their homes because of the harm they’re experiencing from these turbines is wrong. Turbines need to be turned off until the wind industry can prove they’re safe. Politicians need to stand up to the wind industry and protect their citizens.
      The longer it takes to get these turbines turned off, the more legal liability will be brought upon all who are responsible for the harm. How is it that engineers approved these turbines? Who granted the patents?
      In Canada we have Federal Statutes regarding the safety of all manufactured equipment brought into the country.

  6. Some corrections to the above article

    A Defence Department (in Europe) experimented with infrasound (before the US Marines) as a means to quell riots. It was successful but was subsequently banned under the Geneva Convention.

    The narrow band (FFT) analysis method of turbine noise shows peaks in the infrasound region based upon the blade pass frequency and multiples of that frequency. However, our work (presented to the Acoustical Society of America’s Wind Turbine Working Group) showed that there was no Infrasound (as sound waves) present but the results were the analysis of the pulsations.

    We used a filter in the amplifier system to our former chambers to excluse all frequencies below 25Hz going to the speaker arrays and using the reference indoor sound file from the Cape Bridgewater study still get an analysis showing peaks in the infrasound region when there is no infrasound as an actual sound. You can watch the speakers and see the pulsations!

    Our pilot study of 9 sensitve people (presented at the ASA New Orleans conference in December 2017 and at EuroNoise in May 2018) showed those people to be able to sense with 100% accurancy (by a double blind study) when the signal was applied.

    Further studies that we have since conducted have shown the brain to respond to inaudible wind turbine noise (with no infrasound present). The results of this work is to be presented in the ICA 2019 conference in Germany later this year.

    • Tomaž Ogrin says:

      I am sorry I do not understand. Pulsations are also waves through the air. The frequency of pulsations are under 20 Hz or not? Is there resonance in rooms?

    • Noel Dean says:

      My response to Steven Cooper’s comments, which are based on my research over the last 10 years. People’s response when there is very minor or what is said as no infrasound readings is consistent with my findings.

      I must point out that I use SVAN 959, set at around 50 samples a second. I refer to Z weighting as all one third octave sound recorded between 0.8 hz and 20,000 hz. Some people refer this to as infrasound, but this is not true, because because air pressure pulsing can and does have a dramatic impact on high frequency sound in the high frequency, A weighting range and above. It also has a large impact on the C weighting range and above as well. In one case, the Z weighting was not much higher than the C weighting reading.

      When I was assessing a problem situation, I found that the pulsing was from high frequency readings in one third octave was NOT in the infrasound area. The pulsing was readily heard quite loud in fact, which proves to me that the problem is identifiable using A weighting – if in fact the measurement and assessment is done in real time in conditions that bought about the complaint being made. Instead of closing complaints based on fictional predictions instead of factual evidence.

      When I assessed the one third octave graphs, I found that the pulsing occurred in the high frequency area – between 4000hz and 10,000 – at a rate of about 1hz in the range between towers which ranged from about 10-15 dB to 35-45 dB. I believe this change is what causes startle reflex; it is not so much the levels but the change and the rate of change.

      From data collected from inside of a decompression chamber, to that not in a decompression chamber, together with the observations expressed above, I am as certain as I can be, air pressure change is the cause, and not so much the infrasound influence .

      Further to the above, when testing was done after my wife felt ill when going inside of our former house, pulsing sound in the range between 400 hz and 10,000 hz – most prominent up to about 5,000 hz. I believe this was resonating off the walls in this situation. I felt sick as my wife did. The prominent frequencies are that identified in the wind test tonality reports. Wind test reports are being withheld from planning hearings, even though they are public documents. I suspect to prevent the link between the turbines and the cause and effect.

      Adding to the above, I became very ill after being in line with about 6 turbines in a row. I believe the illness is best described the Bends Disease, was from the pulsing I was subjected to for about 15 minutes, until I had to leave the area because of pains in the chest and the head. After a wind farm meeting in regards to Stockyard Hill Wind Farm, the engineer admitted that people who live in line with turbines – which was the case at our house “the picture on front of The Dean Report identifies this situation” – would be badly affected by the pulsing from the turbines.

      I now believe that the pulsing of air pressure had a large part to play in what I consider was partially collapsed lung or lungs consistent with the Bends disease, as I could not bend and lift small weight for any longer than a few seconds without pain and difficultly to breath for about nine years.

      In recent months I received medical advise in regards to pain in the hips was from not being able to breath properly I have done breathing exercises which resolved that problem to a large extent. I had a lot of trouble bending my knees for a number of years as well. That was eased somewhat by having decompression treatment about 5 years ago.

      Adding to our physical health woes was the dishonesty and misleading conduct by Not only wind farm operators and their lawyers, but also by the Council and their lawyer. People in the planning department, the EPA and even the Commonwealth Ombudsman’s Office, a staff member was dishonest when it was claimed that it was not the role of NWFC to resolve complaints by conciliation -when the main role of the Commissioner Mr Dyer was to resolve Complaints in an independent manner. The NWFC relied referencing the Developer’s Managing director false information instead of a proper conciliation meeting. Mr Dyer closed our complaint because there was no evidence, instead of a conciliation meeting which was required to satisfy the independent part of the Wind Farm Commissioner’s role.

      Actions like this do not help our mental health. Our complaint was made in May 2009 and still there’s no independent evidence available for ACCIONA to claim Green Energy Subsidies. But I bet they are not still waiting, and probably obtained in the order of $200 million illegally, by now.

      Because of the knowledge gained and spoken about above, I have now at long last gotten relief from the pain in the head after treatment to release the startle reflex affect. The pain in the lower lungs area has eased after breathing exercises and the pain in the legs is getting less troublesome.

      But I feel my job is not yet complete because I think that for the reasons spoken about above. I think that the larger turbine blades being put too close to where people travel and live will result in deaths, and human destruction for many families for NO fault of there own. But of the so called host lawyers, who pretend to represent hosts when this was not the case, as three host families at Waubra had made noise related complaints. One left like us, and like us, no proper noise investigation had taken place within 5 years of noise complaints being made. To resolve complaints which is a permit condition, and a condition to obtain access to the electricity grid, and obtain green energy subsidies.
